The balanced chemical equation for the reaction between nitric acid (HNO3) and sodium carbonate (Na2CO3) is:
From this, we can see that 2 mol HNO3 reacts with 1 mol Na2CO3. We simply need to perform a mole-to-mole comparison between HNO3 and Na2CO3 to find the mass of Na2CO3 needed to neutralize the acid.
In an accident, a solution containing 2.5 kg of nitric acid was spilled. Two kilograms of Na2CO3 was quickly spread on the area and CO2 was released by the reaction. Was sufficient Na2CO3 used to neutralize all of the acid?
